Background and Objective: Resistance exercises are recognized as an important part of women's fitness and fitness programs. But the effect of resistance training with different intensities on damages and muscle growth in girls is not fully clear. Therefore, the aim of this study was to investigate the effect of 6 weeks of resistance training with two different intensities on selected metabolic parameters among active young girls.Subjects and Methods: Thirty six active student girls (mean age 20.7 ± 1.3 years, weight 58.4 ± 1.3 kg, height 164.1 ± 0.9 cm, and BMI of 23.1 ± 0.5 kg/m2) were divided into three groups: resistance training high intensity (70-90% of one repetition maximum, for 6 weeks; n=12), resistance training low intensity (40-60% of one repetition maximum, for 6 weeks; n=12) and no training control group (n=12). Blood samples were taken before and 24 hours after the end of the protocol to measure the levels of creatine kinase, growth hormone, testosterone, cortisol and insulin-like growth factor.Results: One-way ANOVA results showed a significant difference in growth hormone (P<0.006), testosterone (P<0.05) and cortisol (P<0.03), and non-significant differences in keratin kinase (P<0.17) and growth factor Insulin (P<0.27) between the 3 groups. The result of post hoc test showed a significant increase in growth hormone levels in resistance training groups with high and low intensity compared to control group (P<0.007 and P<0.03), testosterone levels in resistance training group with low intensity compared to control (P<0.05), and cortisol levels in resistance training group compared to control group (P<0.02).Conclusion: The results of this study showed that there is no difference between high and low intensity resistance training on the levels of muscular metabolic indices in active girls.

Background and Objecitve: The current research aimed to determine the factorial structure and reliability of Eating Mindfully Questionnaire (EMQ) among married women with overweight and obesity in Ahvaz.Subjects and Methods: The design of the current research was based on descriptive and factorial analysis. The sample consisted of 200 people recruited using available sampling method according to inclusion-exclusion criteria. The participants answered to the EMQ and the data were analyzed using Pearson Product-Moment coefficient correlation, Cronbach's a, and exploratory (EFA) and confirmative (CFA) factorial analysis. The analyses were performed using SPSS-25 and AMOS-24 software.Results: The results of exploratory factorial analysis. EFAindicated 5 factors like the origin questionnaire. Confirmative factorial analysis. (CFA) supported fitness of the 5-factorial model of EMQ. The Cronbach's a coefficients of the factors ranged from.74 to.84 and it was.8 for the total score. The convergent validity coefficient of the EMQ with the Five-Factor Mindfulness Questionnaire was satisfying.Conclusion: According to the results, the EMQ has adequate reliability and validity and it is useable in research and clinical purposes among overweight and obese population.

Background and Objective: The aim of this study was to compare the frequency domain of selected trunk and neck muscles in children with forward head posture and healthy control ones during running.Subjects and Methods: twelve available male children with forward head (age: 11.7±1.4 years, height: 149.7±6.2 cm, weight: 38.0±4.7 kg) and 16 healthy male children (age: 11.8±1.3 years, height: 148.7±6.3 cm, weight: 39.6±5.4 kg) volunteered to participate in this study. The electrical activity of the selected muscles on the both sides of the body were recorded during running.Results: The frequency amplitude of right serratus anterior muscle in forward head group was higher than the healthy group by 17.6% during stance phase of running. The lower trapezius muscle asymmetry index in the forward head group was higher than that in the healthy group by 105%. Upper trapezius muscle asymmetry index in the forward head group was higher than that in the healthy group by 141% during swing phase of running (P=0.005).Conclusion: Higher frequency content of the right stratus anterior muscle in the forward head group during stance phase of running may be due to weakness of this muscle. Because of the higher asymmetry index in the lower and upper trapezius muscle asymmetry indices during stance and swing phases of running in children with forward head posture compared to healthy ones, it is necessary to design a training protocol for improving the strength symmetry in these muscles in these children.

Background and Objective: Nowadays, the use of probiotic supplements to prevent the production of free radicals has become more common. The aim of the present study was to assess the impact of taking a single course of probiotic supplementation on MDA, total antioxidant capacity and lactic acid in futsalist women.Subjects and Methods: In a semi experimental study, women futsalists of Ahwaz city were selected through available sampling method and divided into two experimental and control groups of 15. Based on the findings of this study, probiotic supplements can be used to reduce the oxidative damage of intense exercise. Subjects with a range of 23 ± 0.60 years, height 167.4 ± 16, weight 87.50 ±7.50 kg, and body mass index of 27.1 ± 4.9, were exercises for eight weeks, three sessions per week and each training session was 75 minutes. Long Supplements and placebo were given to the subjects in the placebo capsule. Blood samples were taken from the subjects in the post-test phase. For statistical analysis, ANOVA and independent t-test were used (P £ 0.05).Results: The results showed that there was a significant decrease in MDA (P £ 0.05) and significant increase in antioxidant capacity (P £ 0.05) among the probiotic supplementation group compared to control group. However, there was no significant difference in reduction lactic acid between both groups (P £ 0.05).Conclusion: According to the findings of this study, the use of probiotic supplementation can improve the antioxidant capacity in athletes.

Background and Objective: Aging and sedentary lifestyle are the risk factors for type 2 diabetes. The aim of the present study was to evaluate the effects of twelve weeks of swimming on glycemic control and plasma apelin levels in older women with type 2 diabetes.Subjects and Methods: In a semi-experimental study, 30 elderly women with type 2 diabetes were selected through purposeful sampling and randomly divided into two equal groups of swimming training and control. Swimming training was performed for 12 weeks, three sessions per week and each session with 50-70% of heart rate reserve. Fasting blood samples were taken before and after the study period. For statistical analysis of parametric tests and t-test and SPSS version 22 was used and the significance level of P<0.05. was considered.Results: After the intervention period, there was a significant decrease in insulin resistance (P<0.001), HbA1c (P<0.001) and plasma apelin (P<0.05) among swimming group compared to control group.Conclusion: Overall, the findings of this study showed that swimming training improves insulin sensitivity and decrease applein levels in elderly women with type 2 diabetes.

Background and Objecitve: Morphological varieties of anatomical structures are different from one ethnic population to another. Awareness of these varieties helps in diagnosis and treatment of related disorders. The purpose of this study was to assess the morphological varieties of the soft palate in lateral. cephalometric images of Iranian patients.Subjects and Methods: In this descriptive analytical study, 385 digital lateral cephalometric images of Iranian patients were investigated in some cities of the country. Demographic data were collected. A classification with 6 groups including leafshaped, rat-tail, butt-like, straight-lined, distorted and crookshaped was used. All the radiographs were analyzed and categorized into six types according to the soft palate morphology by an oral and maxillofacial radiologist. Data were imported in the statistical software (SPSS 20 for Windows, SPSS Inc., Chicago, IL). Demographical data were collected. The morphology types of soft palate were compared among both sexes and different age groups using Chi-square and ANOVA statistical test (a=0∙05).Results: The leaf-shaped soft palate was the most frequent morphology (46.8%) and the least common morphology was crook type (3.6%). There was no significant statistical difference between the morphology of soft palate between genders and different age groups (P>0.05).Conclusion: The leaf-shaped soft palate was the most common morphology in Iranian population. There was no significant statistical difference between the morphology of soft palate of males and females. There was no significant statistical difference between the morphology of soft palate in different age groups.

Background and Objective: Acute myeloid disease is a genetic disorder resulting from a change in the natural mechanisms of the blood precursor cells such as proliferation and differentiation. Mouse Double Minute 2 (MDM2) is an oncoprotein with E3 ubiquitin ligase activity that acts as a potent negative regulator for P53. The most well-known MDM2 gene polymorphism is SNP309polymorphism. Substitution of G nucleotide instead of the T at 309 position increases the expression level of the MDM2 gene. Increasing the MDM2 level decrease the activity of p53 which can lead to cancer.Subjects and Methods: This study was performed on 91 AML blood samples and 115 control blood samples in Khuzestan province. Different genotypes of 309 position of MDM2 genes were determined using PCR-RFLP and Sequeing method.Results: The results show that there is statistically significant association between MDM2 SNP309 polymorphism and AML.Conclusion: In this study the frequency of TT, TG, and GG genotypes was 15%, 41% and 43% in AML group and 62%, 22% and 14% in control group respectively. The genotypic distribution of this polymorphism may be strongly associated with AML.

Background and Objective: In this study, a high-performance liquid chromatography method was developed to determine the concentration of gliclazide in plasma. The Photodiode array (PDA) detector allows for the determination of purity.Subjects and Methods: The mobile phase used in this study was phosphate buffer with pH=3.5 and acetonitrile (HPLC grade) at a ratio of 1: 1 was run isocraticaly through a C18 analytical column. The UV detection was done at 253 nm. Analytical run time was less than 10 min.Results: In the optimum conditions, the calibration curve in the area of 50 to 400 ng/ml, linear with the equation y=28.029x+212.74 and 0.998=R2. Gliclazide was detected within 3.6 minutes by photodiode detector. The limit of detection (LOD) and the limit of quantitative (LOQ) in this method are calculated as 23 ng/ml and 71 ng/ml, respectively.Conclusion: The evaluation of the accuracy and precision of method showed that this method has the ability to determine the amount of gliclazide in plasma, and the method is reliable and fast.

Background and Objective: Stuttering is a disorder that interrupted the fluency of speech with repetition, prolongation and block signs. This study explored the effectiveness of the direct program compared with the other common methods in preschool children with stutter (CWS).Subjects and Methods: The method of this study was a single subject study with an Alternative Treatment Design (ATD). In this study, 6 participants who stutter were selected randomly assigned in three groups. The evaluations were based on severity rating (SR) and percent stuttered syllables (%SS) assessments. The goal was to determine which of the programs reduced the severity of stuttering more effectively.Results: For children in all groups the ratings of the severity of stuttering (SR) and the percent stuttered syllables (%SS) were reduced. The percentage of non-overlapping data (PND) of the three interventions showed that the differences between these programs were not significant.Conclusion: The findings of the present study showed that direct, indirect, and combined programs were effective in reducing the severity of stuttering in preschool children who stutter. In other hand, early intervention is very important and effective in treatment of stuttering in preschool children who stutter.

Background and Objective: The purpose of this study was to investigate the effect of 8 weeks of neurofeedback and pilates training on the balance of children with Down’s syndrome.Subjects and Methods: The sample consisted of 20 children with Down’s syndrome (average age 12 y) who were studying in the exceptional school in Kermanshah. Subjects were randomly divided into two groups: neurofeedback and pilates (n=10 each). The first group received refractory training for 8 weeks and the second group underwent pilates training. The 8-channel Procump device was used to carry out the neurofeedback training. Berg balance test was used in both group vs of pre- and post-test. To compare the two groups, independent t-test was used at the significance level of 0.05.Results: The results showed that both types of training significantly improved the balance of children, but the comparison between the two groups showed that the pilates training had a greater effect on the balance of children than the neurofeedback training.Conclussion: According to these results, it can be suggested that exceptional children’s’ centers and parents can use both types of training to improve children’s’ balance.
